This change looks fine, but is there a way to see how much performance has improved?
I checked the logs using this debug code(c029303), but I don't know what number to use to compare it to trunk...
For example, below is the log output immediately after reloading the browser for a post with 256 image blocks.

@t-hamano, this is a micro-optimization; I don't expect it to have a big impact on its own. But similar optimizations add up in the end. Here's a similar PR for Gallery block #57240. P.S. Code from c029303 only logs after 1000 subscriptions. You won't see a difference for small improvements like this. |

I see, thank you for teaching me 👍

What?
PR combines two
block-editorstore subscriptions into one.Why?
Reduces the number of store subscriptions each time the Image block is rendered. See #54819 (comment).
How?
I just moved
multiImageSelectioninto the existinguseSelectfor the block editor store. It doesn't depend on theimagevalue, so there is no need to group them together.Testing Instructions
